| 英文摘要 | Cu-56 is close to the waiting- point nucleus 56Ni and lies on the rapid proton capture (rp) process path in Type I X- ray bursts (XRBs). In this work, we obtained a revised thermonuclear reaction rate of 55Niop; cthorn 56 Cu in the temperature region relevant to XRBs. This rate was recalculated based on the recent experimental level structure in 56Cu, the recently measured proton separation energy of Sp = 579.8(7.1) keV, together with shell- model calculation, and the mirror nuclear structure in 56Co. The associated uncertainties in the rates were estimated by a Monte Carlo method. Our revised rate is significantly different from the recent results, which were partially based on experimental results; in addition, we found that a result in a previous work was incorrect. We recommend our revised rate to be incorporated in the future astrophysical network calculations. |
